LANCASTER >> An actor who appeared in the children’s television series “Power Rangers Samurai” was sentenced today to six years in state prison for fatally stabbing his roommate with a sword during an argument over the defendant’s girlfriend.

Ricardo Medina, 38, pleaded guilty March 16 to voluntary manslaughter for the Jan. 31, 2015, killing of Josh Sutter, 36, at the home the two shared in Green Valley.

The two men had gotten into an argument about Medina’s girlfriend and the dispute turned physical, with Medina stabbing Sutter multiple times with a sword, according to the Los Angeles County District Attorney’s Office.

Medina was initially arrested shortly after Sutter’s killing, then released after prosecutors asked for further investigation into the man’s death. He was re-arrested in January 2016 on a murder charge, which was dismissed as a result of his plea.

Sutter’s father, Donald, spoke out during the sentencing hearing.

“We also hope that everyone that looks at Ricardo from now on will never see him as a celebrity, but as nothing more than a cold-blooded killer,” he said.
